1 /* We actually DON'T need Objective-C for most of this file.
2 * GetWindowTitle() is the only function that really needs it.
3 * (and even then, we can use the C bindings for it...)
4 *
5 * However, being able to use the Foundation classes makes things
6 * so, so, so much easier, and so I've decided to make this file
7 * in Objective-C++.
